Need more sound, 50Ton shay TRACK POWER

[bill Bagley]

On my home track the sound is anemic. Went to the Houston G Gauger tracks yesterday. With other locomotives running it was impossible to hear.
Consensus has to be a way to turn it up. Have looked all over, can't find it. Nothing visible inside the Tanks? Nothing obvious outside the engine.
Literature states Volume is adjustable. My best guess, only with a DCC Decoder?
I received my engine new in the box, it had a set of Dwgs & a Spectrum Quick Start guide in which I find reference to a users guide. Does such exist?

Thanks
Bill

Found the answer, gotta buy a DCC system to change the Volumn. NO "knob" or switch to turn it up or down.
Not sure if I went to someone with a DCC system & turned it up, it would still be up when I came back to track power.
Otherwise it is a nice unit, the quality is a "8" or so.
My 2 truck "B" Shay is a "5" .
Anyone wanting a 2 truck, $200. plus shipping. Have the original box plus a box to put it in. Consider trade, need cars, and at leat a 8' prefer 10' circle or more of track.
